WebAnswer (1 of 2): Raindrops start to form in a spherical structure due to the surface tension of water. This surface tension of water that makes the molecules sticks together. The reason is the weak hydrogen bonds between water molecules. On smaller raindrops, the surface tension is stronger than ... WebThe spherical shape of water drops Surface tension is a property for liquids and arises from intermolecular forces of attraction. One can notice that a molecule in the interior of the liquid is attracted equally from all directions by the molecules around it.
Web1 day ago · The refractive index of the non-absorbing surrounding medium n m was assumed to be that of water, i.e., n m = 1.333 [51].The refractive index of the non-absorbing ECM was taken as n ECM = 1.36 corresponding to glycoprotein hydroxyproline [49], [52], one of the main constituents found in the ECM of Volvocaceae [53].Unless otherwise noted, … WebMar 7, 2011 · High in the atmosphere, water collects on dust and smoke particles in clouds. Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules. On smaller …

WebA droplet of water forms a spherical shape, minimizing contact with the hydrophobic leaf. The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and exclude water molecules. [1] [2] The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar ...
